Multi-rate low power 10-Gigabit physical layer devices

Broadcom Corporation launched the new family of 65 nanometer (nm), low power, 10 Gigabit (10G) physical layer (PHY) devices that support data rates ranging from 9.953 Gigabits per second (Gbps) to 11.35 Gbps.

The devices are BCM8154 and BCM8156 transceivers, and as well as the BCM8108 and BCM8109 multiplexer and de-multiplexer that operate in conjunction with either the BCM8154 or BCM8156 solution.

These new devices support multi-rate applications including OC-192 SONET/SDH, 10 Gigabit Ethernet (10GbE), 10G Fiber Channel (10FC), and optical transport networks (OTN).

The new family of devices is designed to reside within 10G hot-pluggable modules and high density line cards supporting optical switches and routers within metropolitan area networks (MANs), multi-service switching platforms, add/drop multiplexors (ADMs) and long-haul dense wave division multiplexing (DWDM) transport equipment.

1. The BCM8154, with the BCM8108 and BCM8109, provides power savings along with performance that enables the development of high performance 300-pin MSA modules, especially in a small form factor (SFF).
2. The BCM8156 10G transceiver is targeted for high density multi-port line cards that support SONET/SDH, OTN, 40G and 100G applications, for use with XFP and SFP+ optical modules.
3. Power dissipation of less than 600mW
4. Low jitter generation of less than 200 femto-seconds (or 2mUI RMS)
5. BCM8154/BCM8156 are fully integrated MSA-compliant, multi-rate SONET/SDH, 10GbE, 10FC and forward error correction (FEC) optical transport network transceivers that operate at OC-192 (9.953 Gbps), 10GbE (10.3125 Gbps), 10FC (10.513 Gbps) or FEC data rates (i.e. 10.664/ 10.709/11.096/11.318/11.352 Gbps).
6. The BCM8154 supports both non- return to-zero and duo-binary applications, and includes transmit pre-emphasis and receive equalization for ISI compensation on long FR-4 traces in line card applications.
